Laser isotope separation of 176Lu through off-the-shelf lasers

Abstract We propose a novel and simple method for the laser isotope separation of 176Lu a precursor for the production of 177Lu medical isotope. The physics of the laser-atom interaction has been studied through the dynamics of the atomic level populations using the density matrix formalism. It has...
